US 2026/0054934 A1 · OMNIDIRECTIONAL WHEEL AND CONVEYING INSTALLATION

Abstract

The invention relates to an omnidirectional wheel (10) with a center shaft that extends along a center shaft rotational axis (A12) and a bearing drum (24) that can be rotated about a bearing drum rotational axis, at least three first-set rollers that are mounted on the bearing drum (24) such that they can be rotated about a first-set roller rotational axis (A14.i), which extends transversely to the center shaft rotational axis (A12), are arranged around the center shaft (12) at an angular distance from each other and each have a helical-toothed first-set roller outer thread (18), at least three second-set rollers (16.i), which are mounted on the bearing drum (24) such that they can be rotated about a respective second-set roller rotational axis, which extends transversely to the center shaft rotational axis (A12), are arranged around the center shaft (12) at an angular distance from each other, in particular with a respective angular offset (φ) to the first-set rollers (14.i) and each have a helical-toothed second-set roller outer thread (20), wherein the rollers at least partially protrude above the bearing drum (24) and wherein the omnidirectional wheel (10) is configured in such a way that a rotation of the center shaft (12) about the center shaft rotational axis (A12) relative to the bearing drum (24) effects a rotational movement of the rollers about their respective rotational axis in the same direction of rotation in each case, wherein the center shaft (12) comprises a drive worm (22) that engages with the outer threads.

Dependent claims

An omnidirectional wheel, comprising:

(a) a center shaft which extends along a center shaft rotational axis,
(b) a bearing drum which is rotatable about a bearing drum rotational axis,
(c) at least three first-set rollers which
(i) are mounted on the bearing drum such that they are rotatable about a first-set roller rotational axis which extends transversely to the center shaft rotational axis,
(ii) are arranged around the center shaft at an angular distance from each other, and
(iii) each have a helical-toothed first-set roller outer thread,
(d) at least three second-set rollers which
(i) are mounted on the bearing drum such that they are rotatable about a second-set roller rotational axis which extends transversely to the center shaft rotational axis,
(ii) are arranged around the center shaft at an angular distance from each other, and
(iii) each have a helical-toothed second-set roller outer thread,
(e) wherein each of the at least three first-set rollers and each of the at least three second-set rollers at least partially protrude above the bearing drum,
(f) wherein the omnidirectional wheel is configured such that a rotation of the center shaft about the center shaft rotational axis relative to the bearing drum (24) effects a rotational movement of the at least three first-set rollers and the at least three second-set rollers about their respective first-set roller rotational axis and second-set roller rotational axis in a same direction of rotation in each case, and
(g) wherein the center shaft comprises a drive worm that engages with the first-set roller outer thread and the second-set roller outer thread.
